DescribeTable

Returns information about the table, including the current status of the table, when
it was created, the primary key schema, and any indexes on the table.

Note

If you issue a DescribeTable request immediately after a CreateTable request, DynamoDB might
return a ResourceNotFoundException. This is because DescribeTable uses an eventually
consistent query, and the metadata for your table might not be available at that moment.
Wait for a few seconds, and then try the DescribeTable request again.
